Casual ones : You start, get an objective, figure out how to do it, do it, and receive fun.

Hardcore ones : You start, get an objective, die, die, get halfway to finding out where to go, die, find out how to complete said objective, die, die, find the boss, die^2, kill boss, and bask in the glory of your newly received grade A fun ++.

I shall leave you all with the whisperings of a tale, the kind of story one would hear in a small and run down tavern tucked away far from society. This is a tale written in blood and fire, whose very pages seem to scream in the agony of endless madness. Dredged from the bowels of the ground where it should have stayed buried, this tale is given unholy life once more to dance on the edges of your mind. This is the tale, nay, the legend...of Boatmurdered.
